Brotherdan: "I've rejected theories of men that constantly change. A global flood has NOT been conclusively proven to have not happened."
I haven't read this thread so if I'm repeating something someone else mentioned, sorry.
First, brotherdan, the burden of proof is on someone making the statement. Certain absurd things, like the existence of fairies, cannot be disproven. The Biblical account of a global flood can be disproven but it requires a broad knowledge of Geology. So if a Creationist claims that there was such a flood, he should set forth the claims of evidence and then it can be either verified or nullified.
An excellent book to read on the subject of Creationism from a scientific point of view is the book Science and Earth History: The Evolution/Creation Controversy.

This book has over 500 oversize, small print pages dealing with every aspect of the subject including Noah's Flood.
As far as men's "theories" changing, correction is a necessary part of all scientific endeavor. First the basics and then the details have to be ironed out as new facts come to light. The basics of Evolution haven't changed since Darwin, with the exception of his Gradualism versus Stephen Gould's Punctuated Equilibria.
If the basic teachings were never to change, all scientific progress would come to a permanent halt. Keep in mind that it is the so called changing theories of man that have allowed for all the technological gadgets we have. The Bible, on the other hand, is not supposed to change (At least in the past 1800 years.) but that does not make it true.
